SAW-SET.

SPECIFICATION forming part of Letters Patent No. 623,544, dated April 25, 1899. Application filed Decemher'lhhl898. Serial No. 699,295. (No modem To a7] whom it may concern.

Be it known that FRANK HIXSON, acilizen ofthe United States, residing at Ashland, in the county of Ashland and State of Ohio, have invented certain new and useful Improvements in Saw-Sets; and I do hereby de- 7 clare that the following is a full, clear, and

exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the figures of reference marked thereon, in which-- Figure 1 is a perspective view showing a saw placed in proper position for setting the teeth. Fig. 2 is an edge view showing a portion of the base or bed and. showing the lever and die in position for use upon flue saws. Fig. 3 is a top view of a portion of the bed or base, showing one of the anvils. Fig. 4 is an edge view showing a portion of the base and the die in proper position to act upon the tooth of a saw, also showing a portion of the saw-blade placed in proper position.

The present invention has relation to sawsots; and it consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claims.

Similar numbers of reference indicate corresponding parts in all the figures of the drawings.

In the accompanying drawings, 1 represents the bed or base, which is formed of any desired length, reference being had to convenience in handling and operating. The bed or base 1 may be provided with the block 2, to which block is attached the post or standard 3. The bed or base is also provided with the anvils or inclined ledges 4 and 5, which inclined ledges are for the purposeof giving to the teeth of a saw the desired set by means of the dies 6 and 7. To the top or upper end of the post or standard 3 is pivotally attached the lever 8, which lever may be of any desired length, reference being had to convenience in operating. Tothe lever 8 and a short distance from its pivoted end is pivotally attached the die 6, which die extends a short distance above the lever 8, for the purpose hereinafter described. The bottom or lower end of the die is provided with the inclined end 10, which corresponds with the inclineof the anvil or ledge 5.

For the purpose of preventing the saw-blade from springing or buckling during the time the teeth are being set the die G is provided with the flange 11, which flange is provided with a straight bottom end 12.

In use the saw designed to be operated upon is placed in the position illustrated in Fig. 1, and when the proper tooth has been brought under the die 6 the lever 8 is forced down- Ward, carrying with it the die, and for the purpose of fixing the set of the teeth the top or upper end of the die 6 may be struck with a hammer.

For the purpose of bringing the teeth of the saw'in proper relative position with reference to the die 6 and the anvil 5 the gages 13 areprovided,which gages are adj ustably attached to the cross-bar 14, said cross-bar being attached to the bed or base 1 in any convenient 7o and well-known manner. For the purpose of providing adjustment for the gages 13 they are each provided with the elongated slots 15, through which elongated slots the screwthreaded posts 16 are passed, and upon which 7 5 screw-threaded posts the thumb-nuts 17 are located, it being understood that the screwthreaded posts 16 are to be attached to the cross-bar 14. After the gages 13 have been brought to the desired point of adjustment the thumb-nuts 17 are turned so as to securely clamp the gages 13. 7

When it is desired to use the device for setting fine saws, the lever S is brought into the position shown in Fig. 2 and the die 7 connected to said lever, it being understood that the die 6 is to be removed when the die 7 is brought into use, which is done by removing the pin 9. The die 7is also provided with the flange 19, which flange has the 0 straight lower end 20 and is for the purpose of preventing the saw -blade from being sprung or buckled during the time the teeth are being set. For the purpose of giving the teeth the desired amount of set the upper 5 face of the anvil 5 is provided with the gagelines 21 and the gages 13, set so as to bring the point of the teeth to the proper gage-line when the points of the teeth are brought in contact with the ends of the gage.

It will be understood that by changing the adjustment of the gages 13 a greater or less IOO part of the teeth will be brought over the anvil, reference being had to the adjustment of the gages 13.

In Fig. 1 I have shown the invention applied to use for setting the teeth upon what is commonly known as a cross-cut saw; but it will be understood that my invention can be used for circular saws, the gages 13 being set so as to bring the teeth in proper relative position with the anvil 5. For the purpose of holding the saw-blade the adjustable block 22 is provided and is connected to the bed 1 by means of the screw-threaded post 23 and the thumb-nut 2 1, this block being for the purpose of preventing the saw-' blade from being moved backward after it has been properlyadjusted with reference to the gages 13.

Having fully described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. The combination of the bed or base 1 prothe anvil 5 provided with the gage-lines 21 and the gages 13, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

FRANK IIIXSON.
